FP instances disappearing when reopening scene
« on: March 05, 2019, 04:22:38 PM »
Hi, yesterday I updated my ForestPack version from 6.1.5 to 6.1.6. I'm currently working on an exterior rendering, and when I re-open the .max (3ds max 2016) project the ForestPack objects disappear from my scene. It's the first time this is happening to me (I use FP since version 6.1.2).

As you can see from the attached images:
1 - when I open the scene only one FP object appear (the pebbles in the road in the top part of the image);
2 - FP object (for example Forest005) appear when I select it in Scene Explorer and after I go to the Modify Panel, but is not correct;
3 - the correct version of the object appear only after reapplying a preset I saved (in this case "erbaMix001", thank God I saved it!), you can see that in the image the position, number and scattering of the proxy boxes are different.

Same thing with the upper section of the hill, on top part of the image:

4 - FP object (in this case Forest004) appear when I select it in Scene Explorer and after I go to the Modify Panel, but is not correct;
5 - the correct version of the object appear only after reapplying a preset I saved (the same "erbaMix001"), you can see the position, number and scattering of the proxy boxes are different (and now they are correct).

Any suggestion? How can I be able to open and work on scenes correctly from the start as with the previous FP versions?
Thank you

Hi,

Sorry to hear you're facing these troubles. Would you mind to send us your scene to have a look at it here? Thanks in advance.

Best regards,

Ok, thank you, I'm sending you the scene file using Wetransfer. I cleaned it up a bit, and I'm sending no maps, the scattering is based only on face IDs of the poly objects. The scattered items (grass and rocks) are from the basic library.

Hi, thanks for the scene.

Checking it, i see the parameter which stores the distribution map is not correct (it is "0"), for the affected objects. That causes the FP distribution is empty when scene is loaded.
But when you select the FP object, the plugin detects this problem, and automatically assign the default distribution map ("Dense").

We are investigating why the distribution map is set to a wrong value.

Meanwhile, if the problem happens again, you can fix it easily editing the FP object and selecting the Distribution Map manually.
Once saved the scene, the FP object should keep the right Distribution map.

I apologize for any inconvenience.

Thank you for checking.
I did what you said, I re-opened the scene, and checked the Distrubution Map.
It was on Image>Dense, but I need the Full setting. So I switched to Full and the FP objects appeared and correctly matched the preset "erbaMix001" that I saved.
So then I saved a second preset ("erbaMix002") and resaved the scene (I thought: maybe I changed the Distribution Map AFTER saving the preset?), but when re-opening again the last saved max file scene the issue persists, no scattered objects are visible and the Distribution Map is set back to Dense.......
Maybe there's something buggy in the plugin setting the Distribution Map / Saving Preset functionality?....
Waiting for a solution...

Ok, problem seems to be in the Presets feature. We'll check it.

Anyway, i would suggest you use the Library Browser to store your presets, instead the "General->Presets".

This one is very limited because cannot save all parameters from the Forest object, and practically we keep it only for compatibility.
It was created before the Library Browser supported to store presets.

It's strange because in that scene I have 3 FP objects: Forest003 (the road), Forest004 (upper hill) and Forest 005 (lower grass field).
When I open the scene Forest003 opens and displays correctly, with correct Distribution Map set to Full.
Forest004 and Forest005 do not (they always switch to Dense)...
